Modernizing use of regression models in physics education research: A review of hierarchical linear modeling [PDF]

open access: yesPhysical Review Physics Education Research, 2019
[This paper is part of the Focused Collection on Quantitative Methods in PER: A Critical Examination.] Physics education researchers (PER) often analyze student data with single-level regression models (e.g., linear and logistic regression).

HLMdiag: A Suite of Diagnostics for Hierarchical Linear Models in R

open access: yesJournal of Statistical Software, 2014
Over the last twenty years there have been numerous developments in diagnostic pro- cedures for hierarchical linear models; however, these procedures are not widely imple- mented in statistical software packages, and those packages that do contain a ...

Bambi: A Simple Interface for Fitting Bayesian Linear Models in Python [PDF]

open access: yesJournal of Statistical Software, 2022
The popularity of Bayesian statistical methods has increased dramatically in recent years across many research areas and industrial applications. This is the result of a variety of methodological advances with faster and cheaper hardware as well as the ...

G-optimal designs for hierarchical linear models: an equivalence theorem and a nature-inspired meta-heuristic algorithm. [PDF]

open access: yesSoft comput, 2021
Hierarchical linear models are widely used in many research disciplines and estimation issues for such models are generally well addressed. Design issues are relatively much less discussed for hierarchical linear models but there is an increasing ...

Optimal shrinkage estimation in heteroscedastic hierarchical linear models [PDF]

open access: yes, 2015
Shrinkage estimators have profound impacts in statistics and in scientific and engineering applications. In this article, we consider shrinkage estimation in the presence of linear predictors.

Hierarchical Generalized Linear Models

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1996
SUMMARY We consider hierarchical generalized linear models which allow extra error components in the linear predictors of generalized linear models. The distribution of these components is not restricted to be normal; this allows a broader class of models, which includes generalized linear mixed models.

Violation of the Sphericity Assumption and Its Effect on Type-I Error Rates in Repeated Measures ANOVA and Multi-Level Linear Models (MLM)

open access: yesFrontiers in Psychology, 2017
We investigated the effects of violations of the sphericity assumption on Type I error rates for different methodical approaches of repeated measures analysis using a simulation approach.

Increased interpretation of deep learning models using hierarchical cluster-based modelling.

open access: yesPLoS ONE, 2023
Linear prediction models based on data with large inhomogeneity or abrupt non-linearities often perform poorly because relationships between groups in the data dominate the model.

The supervised hierarchical Dirichlet process [PDF]

open access: yes, 2014
We propose the supervised hierarchical Dirichlet process (sHDP), a nonparametric generative model for the joint distribution of a group of observations and a response variable directly associated with that whole group.
